I'm getting audio sync issues quite frequently using the official HDHR app on my Fire TVs. Changing the channel and back again will fix for about 20 minutes then it goes out of sync again. Anyone else having this?

I see it as well. If AC3 passthru is enabled the video usually locks up while the audio keeps playing. If AC3 is disabled the video keeps going but gets out of sync and quickly becomes unwatchable. Skipping forward or back will fix the sync issue, but the skip is to some random spot, not the 30 second move it should be. This is on the v3 pendant.

I've reported audio sync issues before for live TV. Haven't noticed it on PTV yet but don't watch it that often. I'm still in the process of cutting off my cable so I still use the normal channels most of the time

I experience the issue on my Shield devices so don't think it's just the firestick. It also happens on Live Channels.

After over a year of use with little issues. Over the last week I have been seeing sync issues on our fire 4K. What I don’t understand is why? No hardware changes. No service change. So by elimination something has changed in the software from Amazon or SD. I don’t know but I assume that Amazon put out betas of the fire firmware to all the app developers? If there is a problem with a Amazon update could SD post a warning. I’m amazed at the consumer good manufactures apparent acceptance of releasing poor code. There seems to be quite a few issues with each software release. I work in the Auto industry. A modern car has millions of lines of code. If the auto industry behaved this way where’d see hundreds of car on the side of the road every day.
